鸡肠毒综合症病因及防治

Causes and Prevention of Chicken Enterotoxic Eyndrome

鸡肠毒综合症是指由细菌、病毒、球虫等多种病原微生物在繁殖致病中产生大量毒素,毒素穿过肠壁进入血液循环系统,造成血液中的毒素含量显著升高,蛋鸡死亡率升高的一种临床表现。临床上肠毒综合症和鸡肠炎的症状十分相似表现出严重的腹泻症状,但是肠毒综合症是在肠炎发展到一定基础上产生的一种复杂疾病。近年,随蛋鸡养殖产业不断向前发展,肠毒综合症的发生原因日趋复杂,且多发生在120日龄后的产蛋鸡群中,严重影响鸡的正常生长发育。该文主要论述鸡肠毒综合症的发病原因和防治措施。

Chicken enterovirus syndrome is caused by many kinds of pathogenic microorganisms,such as bacteria,virus,coccidiosis,which produce a large amount of toxin in the course of reproduction,a clinical manifestation of increased mortality in laying hens.The clinical symptoms of enterovirus syndrome are very similar to those of chicken enteritis,but enterovirus syndrome is a complex disease which develops to a certain extent.In recent years,with the development of layer breeding industry,the causes of enterotoxigenic syndrome become more and more complicated,and it often occurs in layers after 120 days of age,which seriously affects the normal growth and development of chickens.This paper mainly discusses the causes of chicken enterovirus syndrome and its prevention and control measures.
